Package box with removable pad

ABSTRACT

A package box with removable pad includes a box body and a plurality of pads mounted to the box body. The box body includes a bottom board and a plurality of side boards perpendicularly connected to the bottom board. The plurality of pads is mounted to the side boards. Each of the pads includes a main body and mounting sections connected to the main body. The side boards form mounting slots corresponding to the mounting sections. The mounting sections are received in the mounting slots to mount the pads to the box body. The package box with removable pad of the present invention uses pads that are provided with mounting sections engageable with mounting slots formed in the box body to allow the pads to be mounted to the box body in a removable manner with a simple operation so as to improve yield rate of assembly.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of packaging, and in particular to a package box with removable pad.

2. The Related Arts

In the field of manufacture of liquid crystal display devices, the manufacture of liquid crystal display devices includes a process of assembling, which assembles various components, including a liquid crystal glass panel, a main control circuit, and an enclosure, together. These components are each manufactured in advance and packaged for being later assembled to form a complete liquid crystal display device. The liquid crystal glass panel, after being manufactured, is packaged in a liquid crystal glass panel package box and then shipped in box to a corresponding assembling station. Commonly used package boxes include paper boxes and plastic cases. Plastic boxes have better structures and lower prices, but local support strength is poor so that pads must be provided in the package box (especially at corners) to improve internal local support strength of the package box.

A conventional liquid crystal glass panel package box has a structure as shown in FIGS. 1 and 2, which comprises a box body 100 and pads 300 mounted inside the box body 100. The pads 300 are generally mounted to the box body 100 with adhesives. To prevent detachment of the pads 300, the engagement surfaces of the pads 300 and the box body 100 must both be smooth. The processing cost is thus high. Further, since fixing is made with adhesive bonding, it is not removable and this is disadvantageous for re-work of the pads 300.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

To further expound the technical solution adopted in the present invention and the advantages thereof, a detailed description is given to a preferred embodiment of the present invention and the attached drawings.

Referring to FIGS. 3 and 4, the present invention provides a package box with removable pad, which comprises a box body 2 and a plurality of pads 4 mounted to the box body 2. The plurality of pads 4 is mounted to corner sites of the box body 2 in a removable manner in order to enhance the support strength of the corner sites and thus protecting a liquid crystal glass panel (not shown) received in the box body from damages caused on the liquid crystal glass panel by external forces.

The box body 2 comprises a bottom board 22 and a plurality of side boards 24 perpendicularly connected to the bottom board 22. The pads 4 n are mounted to the side boards 24. In the instant embodiment, the side boards 24 are of a number of four.

Each of the pads 4 comprises a main body 42 and mounting sections 44 connected to the main body 42. The side boards 24 form mounting slots 242 corresponding to the mounting sections 44. The mounting sections 44 are received in the mounting slots 242 to mount the pads 4 to the box body 2.

The mounting sections 44 each comprise a first mounting unit 442 connected to the main body 42 and a second mounting unit 444 connected to the first mounting unit 442. The second mounting unit 444 has a size greater than size of the first mounting unit 442. The mounting slots 242 each comprise a first slotted section 244 and a second slotted section 246 in communication with the first slotted section 244. The second slotted section 246 has a size greater than size of the first slotted section 244 so as to allow the second mounting unit 444 to be retained in the second slotted section 246 to achieve a removable combination of the pads 4 and the box body 2.

The bottom board 22 and the side boards 24 of the box body 2 are integrally formed together. Preferably, the bottom board 22 and the side boards 24 are integrally formed of expanded polypropylene (EPP) or expanded polyethylene (EPE). The main body 42 and the mounting sections 44 of each of the pads 4 are integrally formed together and preferably, the main body 42 and the mounting sections 44 are integrally formed of anti-static high-density expanded polyethylene, ethylene-vinyl acetate copolymer (EVA), or an anti-static elastic material. Since the side boards 24 and the mounting sections 44 are both resilient, the mounting sections 44 can be set in engagement with the mounting slots 242 of the side boards 24 with interference fitting to prevent the pads 4 from detaching from the side boards 24 of the box body 2 during transportation so as to effectively protect the liquid crystal glass panel.

The main body 42 of each of the pads 4 is provided with at least one mounting section 44. The side board 24 of the box body 2 forms at least one mounting slot 242 that corresponds to the mounting section 44.

In the instant embodiment, the mounting sections 44 of each of the pads 4 are of a number of two. The second mounting unit 444 has a spherical cross-section. Two mounting slots 242 are provided to correspond each of the pads 4 and the second slotted section 246 is a corresponding cylindrical slot. Each of the mounting sections 44 is received in the corresponding mounting slot 242 in order to mount the pads 4 to the box body 2 in a removable manner.

Referring to FIG. 5, which is a schematic view showing a partial structure of a package box with removable pad according to another embodiment of the present invention, in the instant embodiment, each of the pads 4′ has two mounting sections 44′, which comprise second mounting units 444′ having a trapezoidal cross-section of which the size is gradually expanded toward first mounting units 442. The second slotted sections 246′ are of a corresponding trapezoidal slot, of which the size is expanded toward first slotted sections 244 to provide the same technical effect as that of the first embodiment.

Referring to FIG. 6, which is a schematic view showing a partial structure of a package box with removable pad according to a further embodiment of the present invention, in the instant embodiment, each of the pads 4″ has a single mounting section 44″ having a second mounting unit 444″ that is of a spherical cross-section. A mounting slot 242″ is provided to correspond to each of the pads 4″ and has a second slotted section 246″ that is of a corresponding cylindrical slot. Each of the mounting sections 44″ is received in the corresponding mounting slots 242″ to mount the pads 4″ to the box body 2″ in a removable manner so as to provide the same technical effect as that of the first embodiment.

In summary, the present invention provides a package box with removable pad, which comprises pads that are provided with mounting sections engageable with mounting slots formed in the box body to allow the pads to be mounted to the box body in a removable manner with a simple operation so as to improve yield rate of assembly. Further, the pads are of a simple structure and can be repeatedly usable so as to lower down the manufacturing cost.
